SNAP HOOK Filed May 6, 1929 gwomtoz Patented Mar. 1, 1932 UNITED STATES PATENT I OFFICE- f JOHN B. IBAXTER, OF TROY, NEW YORK, ASSIGNO'RlTO COVERT -MAN'OFACTURING COM-' IANY, F WATERVLIET, NEW YORK, A CORPORATION OF NEW YORK SNAP izoox Application filed May 6,

This invention relates to improvements in snap hooks of the kind known as bolt snaps comprising a tubular body or barrel in which slides a spring pressed bolt cooperating with a hook at one end of the tubular body or barrel and having a thumb piece for oper ating the same, the tubular body or barrel being provided in its forward part at the upper side thereof with a longitudinal slot of said forward slotted end portion so that the sliding bolt is left loose at the forward.

end of the slot free for upward'play out of proper alignment with the bill of the hook. This, as will be appreciated, seriously lessens the efficiency of the device.

26 An object of the invention is to improve the manufacture of snap hooks of the general type referred to, to provide an improved bolt snap in which the tubular body or barrel is so formed as to close the slot at the for- 30 ward end of the barrel and prevent opening or separation of the same by the bolt.

A further object of the invention is to provide an improved bolt snap having the longi-' tudinal slot in the tubular body or barrel closed at the forward end thereof, which will be strong, durable and efficient in use, and

of simple construction, that can be easily y or barrel 1' and after this has been, p

formed, the forward portion of the tubular produced at low cost.

40 vantages thereof, and the particular construction, combination and arrangement of parts comprising the same, will be understood from the hereinafter contained detailed description when considered in con-- Figure 1 is a top plan view of a bolt snap in staggered relation.

constructed inaccordance with the present invention.

Fig. 2 is a side 'elevatiompartly in section. Fig. 3 is a top plan view of the casting'or blank. v 4 '35 Fig. 4 is a section' on the line 44 of Figure 3.

Fig. 5 is a section on the line 5-5 of Figure 2.

Referring to a detail description of the particular embodiment of the invention ilustrated in the drawings, 1 designates the tubular body or barrel having a hook 2 at one end and an attaching eye or loop 3 at its other end. 4 is a-bolt slidable within thetubular' body or barrel 1, having a' tapered forward end portion 5 and provided with a thumb piece 6 which projects outwardly through the longitudinal slot 7 in the forward portion of the tubular body or barrel. 8 designates" a coiled spring interposed between the rear wall 9 of the tubular body or barrel 1 and the rear end of the bolt 4. The tubular body or barrel is of the general construction known as the cored type cast with a core the peripheral wall of the rear portion of the tubular body or barrel being solid throughout. The tubular bodyor barrel is preliminarily formed as illustrated in Figure 3 of the drawings with theopposing side walls of the slot 7" forwardly diverging, with the forward end portion of the barrel open adjoining said slot, and provided with spaced lateral extensions l0,-11,' positioned one in advance of the other stood, permits of the ready insertion of the coiledspring 8 and bolt l'within the tubular body or barrel at opposite sides of the slot 790 are forced toward each other by lateral pressure to bring together the staggered lateral extensions'lO, 11, in close overlapping relation to close the slot 7 at the forward end of '95 of the slot in parallelrelation.

The special construction set forth provides a bolt snap in which the longitudinal slot in-the tubular body or barrel is closed at the forward end thereof, the overlapping exten- 'qoo sions 10, 11, serving to close the slot and to strengthen the forward slotted portion of the tubular body or barrel, the resulting structure being of an eflicient, strong, durable nature that will prevent spreading of the forward portion of the tubular body or barrel, the improved structure being such as to be easily manufactured and assembled.

What I claim is:

1'. A bolt snap comprising a tubular body or barrel with a hook at one end thereof and having a longitudinal slot in its upper side 7 v at its forward part, a bolt slidable in the tubular body having a thumb piece projecting outwardly through the slot therein, and a spring in the tubular body between theback wall thereof and the inner end of the bolt,

andsaid body or barrel having staggered extensions projecting from opposite side-marginal portions thereof forwardly of the slot, i saidstaggered' extensions being disposed in close overlapping relation and closing the slot at approximately the forward end portion of the barrel. 7 2., A'bolt snapcasting including a tubular body or barrel. part with a hook at one end thereof and having a longitudinal slot in its upper side at its forward part, the opposing side walls of said slot diverging from the rear to the front thereof, said body or barrel part. at its forward end'portion being open "adjoining said slot and having spaced stag- 'gered lateral extensionsprojecting from opposite side marginal portionskthereof forwardly of the slot, whereby a longitudinally extending guide slot closed at the forward end portion of the barrel will be provided when the opposite sides of the barrel part at the for-wardendportion thereofare forced laterally toward each other.

3. In the manufacture of bolt snaps, the

method of forming a tubular body or barrel witha hook at one end thereof and with a longitudinal guide slot in its upper side at its forwardpart with the opposing side walls of the slot diverging-from the rear to the front thereof, and with theforward end portion of the barrel openadj oining-s'aid slot and with a lateral extension projecting from one side of its open end portion forwardly of said slot,

and subsequently, after the insertion of the v bolt within the barrel, forcing the opposite sidesof the slotted portion of the barrel at the forward end portion thereof laterally toward each other to complete theforming of the guide slot and bring said lateral extension into position to substantially bridge and close the slot at approximately the forward end of the barrel.

In. testimony whereof I hereunto aflix my signature. 7 I
